Zopangira thovu za PVC zimafunikira kuwonjezera zowonjezera zosiyanasiyana. Lero, lolani wopanga sera akutengereni kuti mumvetsetse kusiyana pakati pa zowonjezera zosiyanasiyana!

1. Stabilizer
Lead salt stabilizer ndi calcium zinc stabilizer ndizomwe zimagwiritsidwa ntchito kwambiri pakupanga thovu la PVC. Ndi zofunika zokhwima za chitetezo cha chilengedwe komanso kukwera mtengo kwa calcium zinc stabilizer, kugwiritsa ntchito calcium zinc stabilizer kunayamba kuchulukirachulukira.
Osakwanira stabilizer, chikasu pa bolodi pamwamba, mkulu brittleness wa phala ndi mankhwala, kuchepetsa mphamvu ndi otsika thobvu mlingo;
Ngati pali zolimbitsa thupi zambiri, mpweya wotulutsa thovu umawonongeka pasadakhale, mpweyawo udzasefukira kuchokera ku dzenje lodyera ndi dzenje la vacuum, ndipo kapangidwe kameneka kamang'amba minyewa kapena kufota;
2. Mafuta akunja Othira mafuta akunja
omwe amagwiritsidwa ntchito kwambiri pazinthu za thovu nthawi zambiri amakhala sera wa parafini ndisera ya PE . Sera ya parafini ndiyosavuta kugwa, kotero sera ya PE imagwiritsidwa ntchito nthawi zambiri.

Kutsetsereka kwakunja sikukwanira, kutentha kwa zone 4 ndi 5 za extruder ndikovuta kuwongolera, ndipo ndikosavuta kupitilira kutentha. Pali matuza, matuza, chikasu ndi akhakula mbale pamwamba pa mbale pamwamba; Kukangana kukameta ubweya kutentha kumawonjezera, kuchititsa kuwonongeka kwa zinthu, chikasu cha mbale pamwamba ndi phala;
Kuchulukira kwakunja kwakunja komanso kuphatikizika kosauka kwapulasitiki kumabweretsa kuchulukira kwa nkhungu ndi mvula pamtunda wamankhwala, womwe umakonda kukhala ndi leucorrhea, makulidwe a khoma komanso kusakhazikika mmbuyo ndi mtsogolo kwa zizindikiro zina pamtunda;
3. Internal lubricant
Kusakwanira kondomu mkati, osauka chuma kubalalitsidwa, mkangano plasticization, zovuta kulamulira mankhwala makulidwe, wandiweyani thovu bolodi pakati ndi woonda mbali zonse, leucorrhea, adhesion ku nkhungu patsekeke ndi kutenthedwa m'deralo zikhoza kuchitika;
Mafuta ochulukirapo amkati, zinthu zotulutsa thobvu, kuchepa kwa kutentha, komanso kusinthidwa kukhala mafuta akunja pansi pa kutentha kwina ndikusungunuka, zomwe zimapangitsa kuti mafuta azikhala osagwirizana;
Mafuta osakwanira amkati ndi akunja, kukhuthala kwamphamvu kwambiri, torque yayikulu yapulasitiki, zomatira zomata za khoma, mzere wonyezimira wachikasu pazakuthupi, kusalala bwino komanso kuchepetsedwa kwamakina a chinthucho;
Mafuta amkati ndi akunja ndi ochulukirapo, torque ya pulasitiki ndi yaying'ono, ndipo kusungunula pulasitiki mwachiwonekere sikukwanira. Ngakhale kuti mankhwalawa ali ndi kusalala bwino, kukakamiza kumamatira kumakhala kosauka, komwe kumakhudza kwambiri makina a mankhwala;
Pali zokometsera zochepa zamkati komanso zokometsera zakunja, nthawi yopangira pulasitiki mwachiwonekere imatenga nthawi yayitali, torque ya plasticizing imachepetsedwa, mankhwalawo ndi ovuta kupanga ndipo amakhala osalimba;
Mafuta ochulukirapo amkati, kuthira kocheperako kwakunja, kufupikitsa nthawi yopangira pulasitiki, kumamatira pakhoma, kukhazikika kwamafuta amfupi, ndikuwola mizere yachikasu pamtengo;
4. Calcium ufa Kashiamu
wopepuka wokhala ndi tinthu ting'onoting'ono pafupifupi 1200 mauna nthawi zambiri ndi oyenera kupanga thovu. Calcium ufa ndi wosavuta kuyamwa chinyezi ndikupanga thovu ndi kupenga pamwamba pa zinthu, zomwe zimakhudza mawonekedwe ndi thupi. Choncho, tcherani khutu kusungirako nyengo yamvula.
Pamene tinthu kukula kwa kashiamu carbonate ndi lalikulu kwambiri, n'zosavuta kusakaniza mosagwirizana, plasticization nthawi osakaniza kuchedwa, ndi wononga makokedwe otsika;
Pamene tinthu kukula kwa kashiamu carbonate ndi laling'ono kwambiri, n'zosavuta agglomerate ndi kusintha kwa particles ang'onoang'ono kuti tinthu tating'ono ting'ono, amene ali ofanana ndi zotsatira za lalikulu kwambiri particles;
Pamene mlingo wa kashiamu carbonate ndi wochepa kwambiri, selo alibe pachimake, chiwerengero cha maselo amachepetsa ndi thobvu mlingo amachepetsa;
Pamene mlingo wa kashiamu carbonate ndi okwera kwambiri, wachibale zili utomoni mu zigawo zikuluzikulu amachepetsa, kusungunula mphamvu amachepetsa, ndi mbale gawo n'zosavuta kuswa thovu;

5. Foaming regulator
Foaming regulator zambiri amatanthauza acrylate processing zina ndi mamasukidwe akayendedwe kukhuthala pamwamba 10. Wood pulasitiki thovu zinthu monga zachilengedwe nkhuni ndi khoma chitetezo bolodi zambiri ntchito mtundu ndi kufulumira plasticization. Wowongolera thovu wokhala ndi pulasitiki pang'onopang'ono komanso mphamvu yosungunuka kwambiri imagwiritsidwa ntchito popanga thovu, makamaka bolodi la nduna.
Wowongolera chithovu ndi wosakwanira, mphamvu yosungunula imakhala yosauka, selo silili lofanana, selo lidzawonekera mu gawolo ndipo kachulukidwe kadzawonjezeka;
Pali zowongolera zotulutsa thovu zambiri, mphamvu yosungunula ndi yayikulu kwambiri, thovu lomwe limasungunuka silingachuluke, kachulukidwe kazinthu kamakhala kokulirapo, ndipo mbaleyo imatha kukhala ndi mizere ya wavy, kupotoza ndi kusinthika;
6. Foaming wothandizila
Kuchuluka kwa thovu wothandizila ndi AC yellow thobvu wothandizila ndi NC woyera thobvu wothandizira. AC imamasula kutentha kwakukulu pakuwonongeka, zomwe zimapangitsa kuti zinthu zikhale zachikasu komanso kununkhira kwa ammonia pang'ono pakuwola; NC imayamwa kutentha pakuvunda, ndipo kuwonongeka kumakhala kopanda kukoma. Chifukwa chake, mitundu iwiri yazinthu zopangidwa ndi thovu nthawi zambiri zimagwiritsidwa ntchito polumikizana.
Kuchuluka kwa thovu wothandizira sikokwanira, chiŵerengero cha thovu ndi chochepa, mankhwala ali ndi thovu ochepa ndi kachulukidwe mkulu;
Ngati chithovu chochuluka chikugwiritsidwa ntchito, mphamvu yosungunuka idzakhala yochepa, mankhwalawa ndi ovuta kupanga, ndipo gawo la bolodi la thovu ndilosavuta kutulutsa thovu; Kupitilira muyeso wina, kachulukidwe kazinthu kamakhala kokulirapo;
Yellow thovu wothandizila ndi zambiri, woyera thobvu wothandizila ndi zochepa, ndi thovu lalikulu ndi lozungulira n'zosavuta kuonekera mu gawo.
Chifukwa chake, mulingo wazowonjezera zosiyanasiyana uli ndi digiri komanso ubale woletsana. Pochita kupanga, tiyenera kudutsa mayeso obwerezabwereza, kupereka masewera athunthu kuti agwirizane ndi zida zosiyanasiyana, kupeza malo abwino kwambiri, kuwongolera mphamvu zosungunuka ndi kuchita thovu, ndikutalikitsa nthawi yoyambira.
